Description

FIELD OF THE INVENTION [0001] The present invention relates to a safety ladder structure for installation of road facilities,

The present invention relates to a safety ladder structure for installing a road facility, and more particularly, to a safety ladder structure for installing a road facility, And a safety ladder structure for installing a road facility having excellent stability and security by allowing the facility manager to use only the facility manager while preventing accidents due to a solid locking device when not in use.

Generally, among the road facilities installed on the road, gantry, a rockfall prevention device or a soundproof wall are installed for entrance and exit of the cut slope inspection passage. In such a road facility, a ladder for lifting and lowering Respectively.

That is, in order to inspect the gantry or inspect the cut slope to inspect the slope or cut slope, the inspectors must go up the ladder installed on the road and inspect the entrance of the inspection gantry on the gantry top And open the inspection road of cut slope.

Accordingly, the present invention is an improved ladder provided on a conventional road, and a ladder installed in a conventional road facility will be described as follows.

A ladder installed in a conventional road facility is composed of a multi-stage reinforcing structure provided in a multi-tiered structure on the support or road side surface of the facility, and the occupant steps on it.

That is, the reinforcing steel structure is composed of a diagonal type steel frame so that a tester can easily step on it. The reinforcing steel structure is fixed to the support in the process of installing the road facilities, or both rear sides of the reinforcing steel structure are inserted and fixed when the concrete is poured.

Therefore, the conventional ladder is constructed such that the steel structure having a diagonal shape protrudes in multiple stages on the surface of a support or a facility, so that the inspector can step on the platform.

However, since the ladder configured as described above is provided to protrude from the outside of the pillar or the road surface, an external person other than the road inspector can easily ascend the ladder to cause an accident while generating anxiety of road traffic, The ladder of the present invention has a serious problem that frequent human injury occurs.
